The world’s infrastructure is crumbling, so we’re seeing a rise in bridges that need to be replaced. That’s good news for the companies that build those bridges and for those of us that enjoy a good demolition video. People have certainly gotten more creative with how these demolitions are filmed and this latest video your about to see gives you the ability to see the same demolition from 4 different angles and in different speeds.
The Merafield Bridge, near Plymouth, England was built in 1969 and has suffered from Alkalai-Silica Reaction, which is commonly referred to as “concrete cancer.” Alkalai-Silica Reaction creates spalling due to a gel being formed inside the concrete that expands with water. As the gel expands, pressure builds up in the structure and the concrete cracks. The demolition of the old bridge is part of a $9.1 million (£6.3 million) project that will also include a brand new 262 foot long (80m) bridge. The new bridge will require 2,503 tons of concrete and 401 tons of steel.
In order to bring down the old bridge, crews drilled 278 holes and packed in 110 pounds (50kg) of explosives, according to the Daily Mail. The end result was a middle of the night fireworks show followed by a giant cloud of smoke. You can watch the incredible footage, uploaded to Youtube by SWNS TV, below:
JPMorgan Chase announced their intentions to tear down their existing 52-story headquarters in Manhattan, New York City early last year. When the demolition is complete, it is widely believed that it will be the tallest building ever to be voluntarily demolished. It’s speculated that the building will be dismantled floor-by-floor, as opposed to imploded, due to obvious safety concerns.
As you may already know, the NBA’s Milwaukee Bucks officially opened their new home, the Fiserv Forum, for the 2018-2019 NBA season last October. That new stadium is being heralded as the “World’s First Bird Friendly Arena,” due to many of the design features. Well, since the new one is open, we can only expect that the old, non-bird friendly (I’m assuming) arena has overstayed its welcome and has to go.
Let’s get 2019 started with the first building demolition by implosion of the year.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
